Abstract
The utility model provides a tool box special for measurement transformer ground resistance. The tool box comprises a box body. A box cover is hinged to the box body. A plurality of partition plates are arranged inside the box body. An inner cavity of the box body is separated into a plurality of storage cases through partition plates. Pay-off spools are arranged inside the storage cases on the two sides of the box body. Two rocking handles connected with the pay-off spools are arranged outside the two side walls of the box body respectively. The front box board and the bottom box board of one storage case in the middle of the box body are connected with each other through a hinge. A lock catch is arranged at the upper portion of the front box board of the storage case. The tool box special for measuring the transformer ground resistance is convenient to carry, the time for measuring the transformer ground resistance is effectively shortened, the problems existing in a transformer can be conveniently and timely found and timely processed, meanwhile, the measuring error is greatly reduced, the number of workers is reduced, and labor intensity during working is reduced.
Description
Technical field
The utility model relates to a kind of tool box, especially a kind of transformer grounding resistance measurement tool box special.
Background technology
At present, before thunderstorm season or peak of power consumption arriving, power supply station wants establishment officer to test the grounding resistance of local all distribution transformers every year, to not meeting will rectifying and improving immediately of rules requirement.According to the regulation of < < transformer operating standard > >, < < rural area low-voltage power technical regulation > >: total capacity is at 100 kilovolt-amperes and above transformer, and the earth resistance of earthing or grounding means should be not more than 4 ohm; Total capacity is at the transformer below 100 kilovolt-amperes, and the earth resistance of earthing or grounding means should be not more than 10 ohm.Measurement of Grounding Resistance is the big event of checking and accepting before transformer installation completion puts into operation.But during due to each measurement, operating personnel need to carry several survey tools, carry very trouble, meanwhile, measuring electric wire is entwined together mutually, takes apart and smoothes out with the fingers along all very consuming time during use.And by measuring operation standard flow process, manual retractable cable 2 people, fixing and remote indication instrument needs 2 people, and the human resources that take are larger.When running into wind and rain weather or the irregular situation in ground, instrument is rocked and is swung greatly, easily causes the data of measurement inaccurate.
Summary of the invention
The purpose of this utility model is to provide a kind of transformer grounding resistance measurement tool box special, can special-purpose cranking bar, draw drum, meter specially case and drop bar be all combined in a tool box handled easily personnel, improve the accuracy rate of operating efficiency and measurement data.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: transformer grounding resistance measurement tool box special, comprise casing, on casing, be hinged with case lid, it is characterized in that: in described casing, be provided with a plurality of dividing plates, the inner chamber of casing is separated out a plurality of matter storage lattices by dividing plate, in the matter storage lattice of casing both sides, be provided with draw drum, outside the two side of casing, be respectively equipped with the crank being connected with two draw drums, between the front boxboard of one of them matter storage lattice in the middle of casing and bottom boxboard, be connected through the hinge, the boxboard top, front of this matter storage lattice is provided with snap close.
Improvement to technique scheme: described casing adopts wood materials to be made.
Beneficial effect:
Use transformer grounding resistance measurement tool box special described in the utility model, easy to carry, by the draw drum folding and unfolding electric current in the matter storage lattice of casing both sides, voltage pole line, shrink freely, conveniently answer hand, save manpower, not limited by surface condition, and stopped electric current, voltage pole line is wound around mutually, the phenomenons such as time and effort consuming, and effectively shortened the time of measuring transformer earth resistance, not only be convenient to the problem of finding that in time transformer exists, process in time, also greatly reduced measure error simultaneously, reduced the labour intensity in staff and work, between the front boxboard of one of them matter storage lattice in the middle of casing and bottom boxboard, be connected through the hinge, in this matter storage lattice, can place instrument, the boxboard in matter storage lattice front is opened and can be measured, instrument is placed stable, solved and rocked vibration problems, thereby effectively improved measuring accuracy, avoided wind and rain weather instrument to damage because of immersion simultaneously, casing adopts wood materials to be made, the convenience, with low cost of drawing materials.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment 1
The utility model transformer grounding resistance measurement tool box special as shown in Figure 1, comprise casing 1, on casing, be hinged with case lid 2, in described casing 1, be provided with a plurality of dividing plates 3, the inner chamber of casing 1 is separated out a plurality of matter storage lattices 4 by dividing plate 3, in the matter storage lattice 4 of casing 1 both sides, be provided with draw drum 5, outside the two side of casing 1, be respectively equipped with the crank 6 being connected with two draw drums 5, between the front boxboard 7 of one of them matter storage lattice 4 in the middle of casing 1 and bottom boxboard 8, be connected through the hinge, the boxboard top, front of this matter storage lattice 4 is provided with snap close 9, described casing 1 adopts wood materials to be made.
